[v4 1/7] dt-bindings: devapc: Add 'vio-idx-num' field to support mt8192

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Nina Wu <Nina-CM.Wu@xxxxxxxxxxxx>

For new ICs, there are multiple devapc HWs for different subsys.
We add a field 'vio-idx-num' in DT to indicate the number of
devices controlled by each devapc.
To be backward compatible with old ICs which have only one devapc
HW, this field is not required. The 'vio-idx-num' info will be set
in compatible data instead.
